Answer:
mode = the most
mean =average of the numbers: a calculated "central" value of a set of numbers. ... add up all the numbers, • then divide by how many numbers there are.
median=The middle number; found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers).
<h3>
Mark</h3>
Now we arrange all Mark's test scores first (arrange in a sequence), so it will become :
71, 74, 76, 82, 83, 94, 94
mode = 94
mean = (71 +74+76+82+83+94+94) over 7
= 574 over 7
= 82
median = 82
<h3>
Irina</h3>
Now we arrange all Irina's test scores first (arrange in a sequence too) , so it will become :
79, 79, 82, 83, 89, 95, 95
mode (there are 2 modes in Irina test) which is 79 and 95 because both of them appears twice.
mean = (79+79+82+83+89+95+95) over 7
= 602 over 7
= 86
median = 83

HOPE IT HELP</h3>
Answer:
125.25
Step-by-step explanation:
5 cube =125
1/2=0.5
0.5 squared =0.25
125+0.25=125.25
Answer:
x = 16
m<Y = 34°
Step-by-step explanation:
∆XYZ is an isosceles ∆. An isosceles ∆ has two equal sides, as well as the bases of the isosceles triangle are congruent. In this case, therefore:
<X = <Z
(6x - 23)° = (4x + 9)
Solve for x
6x - 23 = 4x + 9
Collect like terms
6x - 4x = 23 + 9
2x = 32
Divide both sides by 2
x = 16
m<Y = 180° - (m<X + m<Z) (sum of ∆)
m<Y = 180 - ((6x - 23) + (4x + 9))
Plug in the value of x
m<Y = 180 - ((6(16) - 23) + (4(16) + 9))
m<Y = 180 - (73 + 73)
m<Y = 34°
Answer:
2p+17
Step-by-step explanation:
twice p = p x 2 or 2p
so, 17 more than 2p (meaning 2p is increased by 17) is equal to 2p+17
